The development trend and intelligent upgrade of vibration aging instrument

With the advancement of industry4.0With the arrival of the times, vibration aging instruments are undergoing profound technological changes. Intelligence, automation, and informatization have become the main directions for the development of vibration aging equipment. This article will analyze the development trend of vibration aging instruments and explore the technological innovations brought about by intelligent upgrades.

The intelligent upgrade of the vibration aging instrument is first reflected in the innovation of the control system. The new generation of VSR adopts an intelligent control system based on industrial Internet, which can realize remote monitoring and management of equipment. Through IoT technology, operators can view the real-time operation status, processing parameters, and timeliness of devices from anywhere through their mobile phones or computers. The system also has self diagnostic function, which can automatically identify faults and provide repair suggestions, greatly improving the reliability and maintenance efficiency of the equipment.

In terms of data processing and analysis, modern vibration aging machines are equipped with * data acquisition and analysis systems. The device can collect real-time vibration signals, stress changes, and other data, and establish a mathematical model between the workpiece and process parameters through big data analysis technology. Based on machine learning algorithms, the system can automatically optimize process parameters based on historical data, achieving personalized and precise time processing. This intelligent parameter optimization not only improves processing efficiency, but also reduces reliance on operator experience.

The development of vibration aging instruments is also reflected in functional integration. The new equipment not only performs vibration aging treatment, but also integrates multiple functions such as stress detection, deformation measurement, and quality evaluation. A complete quality control system has been formed through linkage with other testing equipment. For example, automatic stress detection is performed before and after processing to evaluate the timeliness effect in real time, ensuring that each workpiece meets the predetermined quality standards.

In terms of hardware, vibration aging instruments are developing towards miniaturization and lightweighting. The new exciter adopts rare earth permanent magnet materials and precision manufacturing technology, greatly reducing its volume and weight, while significantly improving the excitation force and frequency range. This enables vibration aging technology to be applied in more situations, especially in environments with limited space.

Looking ahead to the future, vibration aging instruments will be more closely integrated into intelligent manufacturing systems through collaboration withMESTheERPIntegrate the management system to achieve full process digital management of the production process. The application of artificial intelligence technology will enable vibration aging machines to have stronger autonomous decision-making capabilities, truly achieving unmanned automated production. These technological innovations will drive the application of vibration aging technology to new heights in the manufacturing industry.

1. The origin of vibration aging

Vibration aging technology originated fromIn the early 20th century in the United States, around the 1950s, the front-end vibration aging instrument was born. At present, vibration aging technology has entered a relatively popular stage in all aspects. For example, VDF Machinery Manufacturing in Germany, Ivan Rove Heavy Machinery Factory in the former Soviet Union, Moer Corporation in the United States, Fanak in Japan, Komatsu Machinery Research Institute, and others are all applying this scientific vibration aging technology to eliminate residual stress! Since the 1970s, China has been paying attention to and experimenting with vibration aging technology. After more than 20 years of exploration and practice. Significant achievements have been made in both theoretical research and exploration of process principles, reaching an advanced level. This technology was developed earlier in Chinamachine toolThe beginning of industry application. Qiqihar Front Machine Tool, Beijing Front Machine Tool, Changsha Machine Tool, Jinan Front Machine Tool, etc. have all experimented with vibration aging technology and achieved good results. Nowadays, vibration aging is not only used in the machine tool industry. In textile machinery, embroidery machinery, mining machinery, papermaking machinery, cardboard packaging machinery, various typessteel pipeThe industries of bearing manufacturing, automotive and shipbuilding machinery, aerospace and petroleum have also been greatly promoted and popularized!

2. The principle of vibration aging

Vibration aging is a method of using external force vibration to generate a certain periodic alternating force inside the workpiece. The force and residual stress of the workpiece are superimposed, exceeding the micro yield limit of the workpiece itself, resulting in micro plastic elastic mechanical changes in the workpiece. This leads to a reduction and homogenization of residual stress. Make the forces acting on various aspects inside the workpiece tend to be basically balanced. Prevent deformation of the workpiece. Improve the fatigue limit of workpieces. Thereby maximizing the practical value of the workpiece itself!

3. Applicability and advantages of vibration aging

Suitable for various metal structural components, carbon structural steel, low-carbon alloy steel, stainless steel cast iron, cast iron non-ferrous metals and other mechanical products as basic components, various welded components, plate types, beam types, shaft types, box type parts. Vibration aging equipment can handle large workpieces ranging from a few kilograms to thousands of tons, as well as special-shaped parts with large size differences in length, width, and height. Vibration aging can improve the tensile performance of workpieces, enhance fracture toughness, increase the fatigue limit of materials, improve the dimensional stability of components, and improve the ability to resist load deformation and other mechanical characteristics! It can also save energy and reduce production costs for enterprises.

4. Implementation of Vibration Aging Process

For vibration aging, the more important parameters are:Support point, vibration mode, excitation point, pickup point, acceleration, natural frequency, and time. Among them, vibration acceleration, resonance frequency, and resonance time are the main parameters that determine the effectiveness of the aging process. Therefore, the national standard for vibration aging technology stipulates that the parameter curve observation method must be used to indirectly evaluate the effectiveness of the vibration aging process. Vibration aging equipment can record and print the pre vibration sweep frequency curve, aging curve, post vibration sweep frequency curve, and pre vibration and post vibration sweep frequency comparison curve of vibration aging. These three curves, as long as they meet the national standards for vibration aging technology, can be evaluated as achieving the effect of aging process.

The essence of vibration aging is stable sub resonance vibration at the low-frequency sub resonance point of the workpieceAbout 15-30 minutes, the resonance peak changes and microscopic elastic-plastic mechanical changes occur internally, thus achieving the aging purpose. The vibration aging equipment records and prints the aging curve, pre vibration and post vibration sweep frequency curves, which intuitively, scientifically and accurately reflect the essence of vibration aging. This parameter curve observation method is a fast and scientific way to evaluate the effectiveness of vibration aging technology. In addition, our process can be combined with static observation method, blind hole method, and thermal aging comparison method to determine the effect.

Vibration aging process

In summary, the process of vibration aging is divided into four steps:
Step forward: Prepare before vibration. Firstly, use an elastic rubber pad to support the workpiece to be aged near its nodal line, and clamp the exciter with a bow shaped fixture at the peak of the workpiece vibration. Use a magnetic seat to attract the sensor to the workpiece and use it for special purposescableConnect the exciter, sensor, and controller together. This step is called the preparation process. There are strict process requirements for the support of the workpiece, the clamping position of the exciter, and the placement position of the sensor
Step 2: Pre vibration scanning. The vibration aging equipment automatically detects the natural resonance frequency of the aging treated workpiece and the amount of vibration energy that should be given to the workpiece through scanning, and draws a curve and specific values. This step is called pre vibration scanning.
Step 3: Vibration treatment. The vibration aging equipment automatically determines the vibration frequency for vibration treatment of the workpiece based on the parameters measured in the second step, and performs vibration aging treatment on the workpiece. During the treatment process, changes in vibration parameters and residual stress of the workpiece are detected at any time. When the residual stress is no longer eliminated, the treatment process is stopped in a timely manner. This step is called the time processing procedure.
Step 4: Post vibration effect test. After the vibration treatment is completed, the vibration aging equipment automatically re checks the parameters of the workpiece being aged, in order to determine the vibration aging effect according to the national machinery industry standards. This step is called post vibration scanning.
